[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1 to 7 The utility model provides an adjustable skid-mounted heater, comprising a support frame 2 and a heater body 1 connected to the top of the support frame 2. The heater body 1 is connected to a liquid inlet 3, and the top of the liquid inlet 3 is connected to a connecting plate 11. The connecting plate 11 is sealed and rotatably connected to a rotating tube 4, which can improve the sealing of the connection between the two and prevent liquid leakage. The rotating tube 4 is fixed with a fixed plate 10, and the bottom of the fixed plate 10 is slidably connected to the connecting plate 11. The fixed plate 10 can not only provide support for the rotating tube 4, but also play a guiding role, so that the rotating tube 4 rotates stably. The fixed plate 10 is connected to a positioning mechanism for positioning the rotating tube 4. The positioning mechanism includes a rotating ring 9, a lifting block 16, a guide seat 15, and a positioning column 12. The rotating ring 9 is used to drive the lifting block 16 to rise and fall, and the guide seat 15 is used to guide the positioning column 12. The end of the positioning column 12 is connected to the lifting block 16. The rotating ring 9 is connected to a plurality of positioning heads 22, usually three, with adjacent angles of 120°. The positioning head 22 matches the connecting column 20 at the end of the conveying pipe 5 , and the rotating ring 9 is connected with a positioning bolt 8 for locking the rotating ring 9 .

[0026] When the rotating tube 4 is connected to the conveying pipe 5, the rotation angle of the rotating tube 4 is adjusted according to the position of the conveying pipe 5. Then, the rotating ring 9 can be rotated to drive the three positioning heads 22 to rotate synchronously. The rotation direction is Figure 4In the middle direction (a), the positioning head 22 presses against the connecting column 20, ensuring a secure connection between the first and second interfaces 6 and 7, connecting the delivery pipe 5 to the rotating tube 4. Simultaneously, a downward thrust is applied to the connecting plate 17, driving the lifting block 16 downward, which in turn drives the positioning column 12 downward. The bottom of the positioning column 12 connects to the positioning slot 13, thereby limiting the position of the rotating tube 4 and preventing it from rotating loose. Finally, the positioning bolt 8 is used to lock the rotating ring 9.

[0027] The positioning mechanism also includes a connecting plate 17 and a spring 18. The two ends of the connecting plate 17 are connected to the rotating ring 9 and the lifting block 16 axis. The spring 18 is sleeved on the positioning column 12, and the two ends of the spring 18 are connected to the guide seat 15 and the lifting block 16. When the conveying pipe 5 needs to be disassembled, the spring 18 is in a compressed state. The positioning bolt 8 is loosened to loosen the rotating ring 9. The compressed spring 18 drives the lifting block 16 upward. The use of the connecting plate 17 then causes the rotating ring 9 to rotate, synchronously driving the three positioning heads 22 to rotate. That is, the positioning heads 22 are separated from the connecting column 20, thereby loosening the conveying pipe 5 and facilitating disassembly. At the same time, the bottom of the positioning column 12 is separated from the positioning slot 13, and the rotation angle of the rotating tube 4 can be adjusted again, which is highly practical.

[0028] A vertical groove 19 is provided on the side of the fixed plate 10, and the lifting block 16 is slidably connected to the vertical groove 19. The lifting block 16 slides on the vertical groove 19 and cooperates with the use of the guide seat 15 to make the positioning column 12 rise and fall stably, avoid skewness and offset, and facilitate precise docking with the positioning groove 13.

[0029] The top of the connecting plate 11 is provided with a guide groove 14, and the bottom of the fixed plate 10 is slidably connected to the guide groove 14. The guide groove 14 is an annular structure. When the rotating tube 4 is driven to rotate, the fixed plate 10 can be rotated synchronously. That is, the bottom of the fixed plate 10 slides on the guide groove 14, which ensures the stable rotation of the rotating tube 4.

[0030] A plurality of positioning grooves 13 are provided on the top of the connecting plate 11 , and the positioning grooves 13 match the bottoms of the positioning posts 12 .

[0031] The rotating ring 9 is rotatably connected to the fixed plate 10 , and a plurality of anti-skid protrusions are provided on the outer side of the rotating ring 9 . The anti-skid protrusions can increase the friction with the hand and facilitate the rotation of the rotating ring 9 .

[0032] Rotating ring 9 is provided with a threaded hole that matches with positioning bolt 8. A limiting slot is provided on the outside of rotating tube 4, and the end of positioning bolt 8 matches with the limiting slot. Rotating positioning bolt 8 moves its end downward, and the end of positioning bolt 8 connects with the limiting slot, thereby positioning and locking rotating ring 9.

[0033] The end of the rotating tube 4 is connected to a second connector 7, which is equipped with multiple stopper holes. The end of the delivery pipe 5 is connected to a first connector 6, which is fixedly connected to multiple connecting posts 20, which extend through the corresponding stopper holes. When connecting the delivery pipe 5 to the rotating tube 4, the connecting posts 20 are first inserted into the corresponding stopper holes, which ensures a precise connection between the first connector 6 and the second connector 7, achieving the initial stopper function.

[0034] The connecting column 20 is provided with a pressing groove 21, which matches the positioning head 22. When the positioning head 22 is pressed against the pressing groove 21, a pulling force can be applied to the connecting column 20, so that the interface 1 6 is pressed against the interface 2 7, thereby improving the tightness of the connection between the two.

[0035] Working principle: Drive the rotating tube 4 to rotate, so that the interface 2 7 is in the appropriate position, connect the interface 1 6 with the interface 2 7, and the connecting column 20 runs through the interface 2 7. Drive the rotating ring 9 to rotate in the direction a, and synchronously drive the three positioning heads 22 to rotate. The positioning heads 22 are pressed against the pressure grooves 21 of the connecting column 20, which can improve the tightness of the connection between the interface 1 6 and the interface 2 7, that is, the connection between the conveying pipe 5 and the rotating tube 4 is firm and tight. At the same time, the rotating ring 9 applies a downward thrust to the connecting plate 17, which can drive the lifting block 16 to move downward, and synchronously drive the positioning column 12 to move downward. The spring 18 is in a compressed state, and the bottom of the positioning column 12 is connected to the positioning groove 13 at the top of the connecting plate 11, thereby realizing the positioning and locking of the rotating tube 4 to prevent rotational loosening. Finally, the positioning bolt 8 is used to position the rotating ring 9. When the conveying pipe 5 needs to be disassembled, the rotating positioning bolt 8 is rotated to loosen the rotating ring 9. The compressed spring 18 can drive the lifting block 16 to move upward, and synchronously drive the positioning column 12 to move upward. The bottom of the positioning column 12 is separated from the positioning groove 13, thereby loosening the rotating tube 4. At the same time, the connecting plate 17 applies an upward thrust to the rotating ring 9, which can drive the rotating ring 9 to rotate, and synchronously drive the three positioning heads 22 to rotate, so that the positioning heads 22 are separated from the corresponding pressing grooves 21, thereby loosening the connecting column 20, thereby facilitating the disassembly of the conveying pipe 5. The operation is simple and convenient, and the flexibility is high.
